Powder Coating ?

[Outie Essex]

I have been wanting to powder coat my calipers and perhaps my wheels and some suspension items. My question is this, with how inexpensive some sand blasters and powder coating guns are, why aren't more people doing their own work?
Harbor Freight $119.99 (https://www.harborfreight.com/benchtop-blast-cabinet-62454.html)
Eastwood Powder Coat Gun $174.95 (https://www.amazon.com/Eastwood-Voltage-Powder-Durable-Handheld/dp/B07W9978ZD/ref=sr_1_4?crid=24HIJMDJWXTU4&keywords=eastwood+powder+coat+gun&qid=1578943126&sprefix=eastwood+powder+coat+gun%2Caps%2C770&sr=8-4)
The paint is only $20/lb (https://www.amazon.com/gp/product/B00I1RL11G/ref=ox_sc_act_title_2?smid=AFFM7X34O1N2F&psc=1)

Seems like it could be a lucrative business for a DIYer.

Thoughts?

You still need an oven. As well as the time and patience to finally acquire the skill to do a satisfactory job. That said sometimes cheap tools aren’t he best tool.

I agree about the tools but most of the ones I have seen have decent video reviews. And as far as an over goes, there are tons of super cheap electric ovens for sale used.
As far as the art goes, have you powder coated? What techniques do you recommend?
